"Structure-Activity Relationship"

Mimicking phosphorylation of alphaB-crystallin on serine-59 is necessary and sufficient to provide maximal protection of cardiac myocytes from apoptosis.

AlphaB-crystallin (alphaBC), a small heat shock protein expressed in high levels in the heart, is phosphorylated on Ser-19, 45, and 59 after stress. However, it is not known whether alphaBC phosphorylation directly affects cell survival. In the …

Adrenocorticotropin(1-14)OH-related molecules in primary cultures of rat intermediate pituitary cells. Identification and role in the biosynthesis of alpha-melanotropin.

The structures of the altered alpha-melanotropin (alpha MSH or alpha-N-acetyl-ACTH(1-13)NH2)-related molecules produced by cultured rat intermediate pituitary cells were investigated. Peptide analyses demonstrated that the alpha MSH-related molecules …

Selective loss of alpha-melanotropin-amidating activity in primary cultures of rat intermediate pituitary cells.

The production of alpha-melanotropin (alpha-N-acetyl-ACTH(1-13)NH2 (alpha MSH) in rat intermediate pituitary was investigated using reverse phase high performance liquid chromatography, immunoassays, and biosynthetic labeling. Extracts of rat …
